Best way how to prevent BTC wallet from hackers

[DeAlquezar]

Cols storage or VirtualBox without access to the Internet is the best option in my opinion.

You should use Desktop Wallets.It is safer than online wallets. Because it can store your Bitcoins on your computer’s hard drive instead of on the internet.

Bad advice.  Look up cold storage here, if you have any significant number of coins, storing them on your computer or on the internet (e.g. "the cloud") is a bad idea.

Cold storage in a nice fireproof safe is the way to go.

Use Electrum. Install one in an offline computer and then write down the Master Public key and then install Electrum in an online computer and  choose watch-only mode and enter the Master Public Key. If you want to send BTC, create a raw transaction and then use a qrcode generator and copy-paste the raw tx in it and generate a qr code and scan it with your mobile and copy-paste it and create a document. Now connect your mobile and copy-paste the raw tx to electrum and sign it. Then, copy-paste the signed raw tx to the document. Now you can copy-paste the raw tx and push it through online services like Blockchain.info, Eligius, webbtc.com or Btc.Blockr.io .

You could look into buying a Trezor. Very secure wallets but they're a little pricey. ($120 IIRC)

OR buy BTChip. Its like trezor but the hardware protection is low and there is no screen but still it is very good and cheap.

Paper wallets FTW!
cheapest method ever, always keep a laminated copy just in case.

Interesting, haven't heard of the BTChip before. I'll have to look into it, seems like a great alternative to the Trezor after a few looks at it.

To prevent hackers from stealing you precious coins, try putting the majority of it in a cold storage that isn't connected to the internet. A hard drive or a USB may help you in doing this. Also, try printing those in a paper wallet and have multiple copies of it. Laminate them and keep it in a nice and secure place that you could think of. That is the best and cheapest method in keeping your wallets safe and secure.

What is a Trezor? I've been seeing posts about it lately but I don't know what it is. Is it a kind of an electronic gadget or something? I also saw a post earlier about this Trezor keychains? Correct me if I'm wrong but are they being used as a keychain also? If so, then it's an interesting item!

Trezor is a Bitcoin Hardware wallet which offers great security to your funds in the wallet. Trezor and a paper wallet are the safest ways to prevent hackers to take away the funds.

Paper wallets are a poor mans trezor, I recommend buying a trezor.

Trezor wallets are overkill for people storing 1-10BTC. A trezor cost $119 while a paper wallet cost a few cents yet providing excellent security. If someone wants put 10BTC in a trezor, the person would have to invest ~33% of their BTC just to secure their coins. If they use a paper wallet, it would be less than 0.1% of their 1BTC. They just need a offline wallet and a open sourced wallet generator. No hackers can get your private key if you create the paper wallet on a fresh offline Linux USB drive. To prevent people with physical access to steal your BTC, encrypt the wallet with BIP38 encryption with a strong password. A paper wallet can also be water resistance if you laminate it and make a couple more copies and place them in different geographical locations to prevent fire damage too.

Replace Microsoft Windows with GNU/Linux.

I recommend Tails, then make sure to dedicate the sole purpose of that machine to your wallet and NOTHING else.

Tails is excellent. It does all connections through Tor unless you click on the clearnet browser (correct me if I'm wrong) and great for accessing an electrum wallet using just your seed written down on paper. It even wipes your RAM on shutdown so that no trace of your transactions can be recovered. Every time you boot it starts from scratch (no wallet.dat file or any history left lurking) and doesn't touch your hard disk unless you tell it to through the file manager. It has everything you need for a quick online transmission to the Blockchain and then reboot without a trace.

It gets updated regularly (about once a month) to ensure any security flaws are dealt with and there's a BTC donation address on their home page. If you have a spare $20 worth of BTC to donate I'd recommend you sent them some BTC to keep this gem of an OS going. I've donated in the past and will do again.

It's a little bit slow booting from USB but worth it. Better still, install it on a lockable SD card and flick the switch to 'lock' mode so that you're doubly sure that nothing is altered. Then when a new version comes out unlock your SD and install it before locking it again. Sweet!
